CLOSURE- FOR 'BOTTLES.

Application filed Gctober 11, 1922. Serial No. 593,837.

hattan, in the county and State of New York, have invented a new and Improved Closure for Bottles, of which the following is a full, clear, and exact description.

This invention relates to improvements in bottle closures, and has particular reference to locking means therefor.

An object of the invention is to provide a closure or cap for bottles or vials, particularly adapted to contain perfumes and which is so constructed that the same will be securely maintained in its closing position and will present a neat and attractive appearonce when in place.

Another object is to provide a closure or cap of extremely simple construction, which may be easily and cheaply manufactured.

The above and other objects will appear more clearly from the followingdetail description when taken in connection with the accompanying drawing which illustrates different embodiments of the inventive idea.

In the drawingigure 1 is an elevational view of the in vention;

Figure 2 is a sectional View on the l ne 22 of Figure 1; and

Figure 3 is an elevational view showing a slightly different form of the invention.

eferring more particularly to the draw ing, the numeral 4 indicates a small bottle a vial of cylindrical formation, which 1s :ticularly used for containing perfumes end which is'provided at its open end with slightly reduced and externally threaded neck 5, into which a cork or stopper 6 may be inserted.

The cap orclosure '7 which comprises the essential features of the present invention, preferably made of thinmaterial and fined with a rounded end 8 adapted to en age the stopper 6 to securely maintain the some in closing position. The closure 7 is also of cylindrical formation and its exterior diameter is preferably equal to that of tie vial i so that when the closure is in closclosure will engage the annular shoulder 9 formed by the reduced neck and thus,

., closure.

' lV hat is claimed 1s:

position on the neck 5, the inner end of in the eflect, present a smooth exterior surface which forms a continuation of the body of the vial, thereby producing an article of neat and artistic appearance.

To maintain the closure 7 securely on the neck of the vial, said closure is preferably provided with one or more inpunched locknag pro ections 10 which are rounded and designed to be positioned in the'spaces between the external threads on the neck 5 and engage adjacent surfaces of said threads to prevent displacement of the closure with respect to the vial until said closure is unscrewed from the neck.

7 In the form of the invention shown in loigures 1 and 2 the instruck locking projections 10 are aligned with respect to a plane extending through the longitudinal axis of the vial, while in the embodiment shown in Figure 3, one of these projections may be arranged in said plane while the other is offset with respect thereto. In both instances, the projections are longitudinally spaced to receive the threads of the neck 5 'therebeson of the offset-relation of the projections- 10 that the closure when being applied or removed will be prevented from being shifted laterally'with respect to the longitudinal axis of the neck, which shifting might otherwise result in a buckling or distortion of the As a new article of manufacture, a bottle closure of cylindrical format on having a closed end engage'able with a stopperinounted in the open threaded endof a container to" retain said stopper in position, said closure being of substantially the same diameter as said container and having its wall instruck to provide spaced locking projections, said closure and container forming a cylindrical surface of uniform external diameter free of external projections, said locking projections engaging adjacent threads formed at the open end of said container to
